WDEL's Amy Cherry goes undercover to see the illegal gambling devices in play.

WDEL first identified the pusher or bulldozer machines inside at least two convenience stores at BP gas stations in Wilmington on MLK Boulevard and S. Heald Street and brought them to the attention of several authorities.

The five-foot suspected illegal gambling machines are in plain sight and similar to an arcade game for kids, where you win tickets or tokens for a prize. But this coin-in/coin-out game is illegal because you can win money.

Undercover video obtained by WDEL shows players putting quarters into the slot, they fall vertically onto a shelf behind plexiglass in an effort to push quarters or cash over the edge.

WDEL's exclusive video shows a player winning just $1.25, but the bulldozer machines also contains $100 and $20 bills, you could win, tempting you to play more.

After viewing the video, Lt. Marshall Craft with the state's Division of Gaming Enforcement says, "It does appear to be illegal."

When the machines were described to another top state gaming official, he said, "It sounds a little iffy."

The Attorney General's office refused comment on the grounds that they may have to try the case, if criminal actions are brought.

Wilmington Police told WDEL that the illegal gambling machines aren't "high on their priority list," but WDEL has learned police have visited both locations, demanding store owners remove the machines. Store owners have complied since WDEL has learned both machines in the city are now gone.

WDEL is aware of two other illegal pusher machines at gas stations in New Castle County, in North Wilmington and Milltown.

A similar pusher machine was declared illegal in California last year.
